Exploiting dynamic reaction cell technology for removal of spectral interferences in the assessment of Ag, Cu, Ti, and Zn by inductively coupled plasma mass spectrometry

Characterisation of gas cell reactions for 70+ elements using N2O for ICP tandem mass spectrometry measurements

“…Gases that have previously demonstrated a collisional focusing effect include hydrogen, 12,17 helium, 1,18,19 and NH 3 . 20,21 While the choice of reaction gas is an important consideration for removal of interferences, differences in the types of reaction cells used have shown to have a signicant contribution to the removal of interferences. Koppenaal et al summarized that quadrupole-based reaction cells allow for effective mass-selective ejection of unwanted precursor and product ions but lower transmission and higher scattering losses.…”

Single-cell ICP-MS for studying the association of inorganic nanoparticles with cell lines derived from aquaculture species

“…Standard mode and mass-shift approach were used for the measurement of silver and titanium, respectively. Ammonia clusters of mass-charge ratio 131 (1.0 mL min −1 of ammonia and RPq 0.2 value [ 33 , 34 ]) were used for titanium determinations. The scICP-MS analytical data were processed using an iterative approach aiming the cell event threshold.…”

“…Optimization has implied the study of several parameters to avoid high dissolved background, multi-cell peak coincidence, and possible spectral interferences. The latter task is quite important for titanium determination, and the use of ammonia, previously used as a reaction gas in collision/reaction cell technologies for total titanium [ 31 ] and TiO 2 NP [ 32 ] assessment by ICP-MS/MS and spICP-MS/MS, respectively, has been novelty used for scICP-MS analysis when assessing the titanium content at cells (monitoring the 48 Ti(NH)(NH 3 ) 4 adduct at a m/z ratio of 131) [ 33 , 34 ].…”
